Description

Technical Field

[0001] The present invention relates to the technical field of charging pile design, and in particular to an automobile liquid-cooling charging pile. Background Art

[0002] A charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electric energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging piles are divided into public charging piles and private charging piles, and are divided into AC charging piles and DC charging piles in terms of charging methods.

[0003] When charging, the current will generate heat when passing through the resistor. According to the law of conservation of energy, this part of the electric energy will be converted into heat energy and dissipated into the surrounding environment. Especially for DC fast charging piles, since the power is usually large, the heat generated during operation is more considerable.

[0004] In addition, current car charging piles use a large number of circuit boards and electronic components, such as power modules, inductor modules, etc., which will generate a lot of heat under high current and high voltage working conditions.

[0005] In order to ensure the normal use of the charging pile, a cooling device needs to be installed in the charging pile. At present, a cooling fan is usually used for cooling, which leads to poor cooling effect.

[0006] In order to ensure the normal use of the charging pile and meet the heat dissipation requirements of the charging pile, the present invention proposes an automobile liquid-cooled charging pile. Summary of the invention

[0011] The liquid cooling structure includes a liquid storage tank, a liquid pump and a cooling pipe; one end of the cooling pipe is connected to the liquid storage tank through the liquid pump, which is responsible for sending the coolant in the liquid storage tank into the charging pile body for heat absorption. The cooling pipe is tied together with the cables inside the charging pile body through a cable tie, and returns the heated coolant to the liquid storage tank;

[0012] A heat sink is provided above the liquid storage tank, and two fans are connected to the heat sink to cool the coolant that returns to the liquid storage tank after heating, thereby increasing air flow efficiency and allowing heat to flow out through the heat sink.

[0013] The liquid storage tank is fixedly connected to a first motor, and an output shaft of the first motor is fixedly connected to an agitator, which is used to further increase the air flow efficiency inside the liquid storage tank and improve the heat dissipation effect.

[0015] When the shaft rotates, it can drive the two first bevel gears to rotate synchronously, and then drive the two second bevel gears to rotate synchronously, and further drive the two fans to rotate synchronously, making the operation more convenient;

[0016] The rotating shaft and the output shaft of the first motor are both fixedly connected with pulleys, and a transmission belt is sleeved on the two pulleys. The first motor is connected to the rotating shaft through the transmission belt.

[0017] After the first motor is started, the output shaft drives a pulley to rotate, and under the action of the transmission belt, the two pulleys rotate synchronously, and then drive the rotating shaft to rotate synchronously, thereby saving more energy.

[0020] When the slider slides up and down in the slide groove, the rotating shaft drives the cleaning brush to slide up and down to clean the plurality of heat dissipation grooves; the bristles of the cleaning brush can also be inserted into the heat dissipation groove to push out the dust accumulated on the outside of the heat dissipation groove.

[0021] A rubber wheel is fixedly connected to the rotating shaft, and the rubber wheel is pressed against the inner wall of the charging pile body; when the slider slides up and down in the slide groove, the friction between the inner wall of the charging pile body and the rubber wheel causes the rubber wheel to rotate, thereby driving the rotating shaft to rotate; the rotating shaft drives the cleaning brush to rotate, thereby further improving the cleaning effect.

[0022] A threaded rod is rotatably connected in the slide groove, and the threaded rod is threadedly connected to the slider; a second motor is fixedly connected to the charging pile body, and the output shaft of the second motor is fixedly connected to the threaded rod;
